The Ultra Lightweight Merino Run Quarter Socks by Patagonia a noncushioned, durable running and biking sock affords exceptional performance on the open road or winding trail.

Uncomplicated, just like a good run. This featherweight, noncushioned running/biking sock has a skin-friendly blend of soft merino wool and nylon for exceptional breathability, a cooling airflow and rugged durability. Excellent stretch and recovery lasts the lifetime of the sock; a mesh arch brace provides a snug, no-slip fit. The looped Lintoe construction creates the smallest and flattest seam possible for toe comfort. An over-the-ankle fit protects vulnerable skin.
